Eaton RM4-400 Series magazine (23”/ UL)

The Eaton RM4-400 magazine is a versatile and compact 1U high, 23-inch module that is designed to UL specifications. Fast on-line expansion of rectifiers (hot-swap), dual AC input and suitability for both enclosed cabinet and open frame relay-rack mounting make the RM4-400 series an ideal solution for you to supply front end 48V power to customer equipment or as a building block for integrated systems in custom applications.

Suitable for Enterprise, Access 3G power and Energy Saver Rectifiers

The Eaton RM4-400 rectifier can accommodate both the Enterprise and Access series of Eaton 3G and Energy Saver (ES) rectifiers and can be fitted with up to four rectifiers or three rectifiers and a system controller. It has an output capacity of up to 200 A (actual output is dependent on the rectifier model), however the front-to-back airflow allows two RM4 magazines to be stacked for higher capacity solutions.

Versatile solution

The DC output is via a field wiring termination box to provide an easily accessed connection (take-off) point for flexible cables. AC supply is via two flexible cords (one cord per two rectifier positions) and is suitable for both single-phase and two-phase AC supply applications. This makes the RM4-400 series suitable for both enclosed cabinet and open frame relay-rack mounting. The mounting brackets can be moved along the chassis to provide a wide range of mounting position options for you.
